SPECIFICATION forming part of Letters Patent No. 242,731, dated June 7,1881.

Application led March 1B, 1881.

To all whom it 'may concern:

Beit known that I, LYMAN O. WOOD, a citizen of the United States,residing at Wichita, in the county of Sedgwick and State of Kansas, haveinvented certain new and useful Improvements in Vehicle-Springs; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable thersskilled in theart to which it appertains to make and use the` same, reference beinghad to the accompanying drawings, and to letters or gures of referencemarked thereon, which forma part of this specification, and in which-Figure l is aside elevatioinpartly in section, with the wheels removed,of a vehicle y with my improved spring applied thereto; and

Fig. 2 is a detailed view ofthe spring.

This invention has relation to improvements in vehicle-springs, itsobject being to permit of the equalizin g of pressure upon the springsand the distribution of the bearing-points ot' the springs uponthevehicle-body; and it consists of compound springs the convexities ofwhich are supported in or connected by clips to the vehicle-body, whiletheir inner ends are connected to and adapted to have motion uponspindles or bolts depending from the vehi cle-body, and encircled belowthe` body with springs, substantially as hereinafter more fully setforth and claimed.

Referring to the accompanying drawings, A A indicate the individualsprings of the compound springs, one being arranged upon each side ofthe vehicle. Each spring A is semi-elliptical in form, with itsconvexity supported in a clip, c, suitablybolted thereto, and, in turn,connected to the vehicle-body by aplate, b, bolted to the clip and tothe under side of the body, as seen in Fig. l. The springs A, arrangedin pairs upon each side of the vehicle, the rear springs beingconnected, as shown, or in other suitable manner, to the rear or hindaxle, while, in addition to their attachment directly to thevehicle-body, they `l, in a bridge or arch, c.

(No model.)

are also connected indirectly to the vehiclen bodyattheirinnerends.' Theforwardsprings, likewise directly connected to the vehicle-body, asbefore described, are connected in similar manner as the rearsprin gs tothe bolster of the front axle, while their inner ends are alsoindirectly connected to the body.

The means of attachment for the inner ends of each pair of springsconsists of a plate, c, linked, as at d, to the said ends of thesprings, and fitted to slide vertically upon a bolt or spindle, B,extending up through the Vehiclebody, and seated, preferably, as shownin Fig. Ooilcd around the spindle or bolt B, below the body, is aspring, B', not necessarily, however, a coiled spring,

- which acts downwardly upon the plate .c to sccure it yieldingly inposition upon thebolt.

From the foregoing it will be noticed that asweight is put upon thesprings they will be permitted to bear, not only at their convexity,upon the body, but also upon the center of the body, and thus distributetheir points of bean in gand equalize the pressure upon the springs.

It is also readily seen that greater resiliency is obtained, whichpromotes comfort and ease.

Having thus fully described my invention, I claim and desire to secureby Letters Pat entl. rIhe combination of the semi-elliptical springs A,arranged to connect with the hind axle and forward-axle bolster, andvertical sliding plate O, and bolt or spindle B, and spring B'.

2. The combination of the arch-spring c, springs A A, clips b b, platec, and spindle B, substantially as shown, and for the [purposedescribed.

In testimony whereof I affix my signature in presence of two witnesses.
